Astra Linux – Vulnerability in Linux 5.10, Linux

A flaw was discovered in the Linux kernel. A NULL pointer dereference may occur when the slip driver is in progress to detach at sltxtimeout in drivers/net/slip/slip.c. This issue could allow an attacker to crash the system or leak internal kernel information...

CVE-2026-81001

A flaw was found in the Linux kernel's Serial Line Internet Protocol SLIP driver. A race condition in the slsync function allows for a use-after-free vulnerability, where the driver attempts to access a network device pointer after it has been freed. A local attacker could exploit this to cause a...
